Description

[Detailed Description of the Invention] Industrial Application Field The present invention is a device for gripping and fixing each electronic unit when molding a system combining various electronic units, and for connecting an operating power source to the electronic unit. Regarding power distribution boxes.

Prior Art Conventionally, when attempting to configure various electronic control systems by combining various electronic units,
Connecting terminals corresponding to each electronic unit are provided on the board on which the circuit wiring for the operating power supply and the input/output circuit wiring for each electronic unit are provided, and electronic units assembled separately are equipped with plug-in terminals. As a result, a method was adopted in which these parts were combined and assembled.

In such a case, the conventional electronic system is assembled by inserting the electronic unit 20 into the connector 22 on the board 21 as shown in FIG. They were connected to each other by bus bars 24 disposed therein. However, in a power supply connection circuit with such a structure, it is necessary to assemble each terminal component, which requires a large number of components, which not only requires a large number of man-hours to manufacture the board, but also requires a large height due to the provision of terminals. Another drawback is that it is difficult to make it compact as a whole. Furthermore, it is necessary to prepare circuit boards of different designs for different electronic systems, complicating production management.

Problems to be Solved As mentioned above, in configuring various electronic units, it is necessary to simplify the combination of electronic units and to miniaturize the electronic system.
In response to this need, the present invention seeks to provide a new means for assembling electronic units in place of the substrates used in conventional electronic system assembly.

Means for Solving the Problem The object of the present invention as described above is to provide a system that is composed of a standardized box for accommodating various electronic units, and a frame that connects a combination of a plurality of boxes from the outside. This is achieved by providing a pair of power supply connection terminals and using a power distribution box.

That is, the power distribution box for connecting a power supply to an embedded electronic unit according to the present invention has a convex or concave groove shaped to fit with each other on the outer surface and a pair of terminals for connecting a power supply, and has a housing space for an electronic unit, etc. inside. A polygonal prismatic box having a polygonal column and a frame having a concave groove or convex groove having a shape capable of fitting into the convex convex or concave groove on the inner surface, and a pair of power supply connection terminals as necessary, are combined and fitted together. It was constructed as follows.

The power distribution box of the present invention is constructed as shown in FIGS. 1 and 2. That is, 1 is a box housing an electronic unit 4 inside, and has a convex groove X and a concave groove Y vertically provided on four side surfaces in a shape composed of dovetails and dovetail grooves, etc., and as a whole. It is shaped like a column. Power connection terminals 5 formed of elastic metal plates or the like are provided in pairs on the left and right on the side surfaces sandwiching the protrusion X and the concave groove Y. connected to the power terminal of the The electronic unit 4 is configured, for example, by attaching a relay 7, a resistor hole 8, etc. on a printed circuit board 6, and input terminals and output terminals are connected to a signal connector 9 provided protruding from the bottom of the electronic unit 4. are set up together. The power supply connection terminal 5 has a bending portion 5a for relieving the pressing force inside the box 1, penetrates the wall of the box 1, and is curved in an arch shape on the outside thereof to soften the pressing force from the outside. It is designed so that it can be received easily.

The frame 2 is provided with a groove Y or a convex X shaped to fit with the convex groove X or groove Y of the box 1 on its inner wall surface, so that the frame 2 can be assembled without any gaps while fitting the box 1. It's becoming like that. Also, box 3
is a part where one side wall of the frame body 2 is configured to be removable, and it fits into the protrusion X or groove Y provided on the frame body 2, and also fits with the protrusion X or groove Y of the box 1. A concave groove Y or a protrusion X is provided on the side surface for fitting, and a power connection terminal having a structure similar to the power connection terminal 5 provided on the case 1 is provided on the surface to be fitted with the box 1. A terminal 5 is provided.

The wiring inside the boxes 1 and 3 is arranged as shown in Fig. 3, and is configured so that even if the arrangement of the box 1 is changed in various ways, the power supply polarity will not be connected incorrectly. has been done. A power supply wiring 10 inside the box 3 consists of a common power supply + and a common ground -, and is connected to a power supply connector 11 at the bottom of the box 3.

The frame body 2 has a structure as shown in FIG.
A connection hole 13 facing the housing 3 and a connection hole 14 for the power supply connector 11 at the bottom of the case 3 are provided. Further, a lid 15 is provided via a hinge 16 and is formed to engage with a claw 17 when closed. Although there are no power supply connection terminals provided on both sides of the protrusions X and concave grooves Y provided on the side plate 18 of the frame 2, power supply connection terminals may be provided as needed, and the wiring can be connected with the same polarity. may be connected together.

The power distribution box for connecting a built-in electronic unit power supply of the present invention is constructed by selecting a box 1 in which each of the electronic units 4 necessary for configuring a planned electronic system is built into the frame 2 as described above. Then, the case 3 is fitted into one side of the frame 2, and the lid is put on to complete the assembly.

Effects of the Present Invention As explained in detail above, the power distribution box for power supply to embedded electronic units of the present invention incorporates various electronic units into a box with a standardized shape, and selects one of these as appropriate. By selecting the necessary items and assembling them in the frame one by one, and bringing the power terminals provided on their outer surfaces into contact with each other, the power wiring connections to these electronic units are automatically completed. This is what I did.

Frames are available in various shapes and sizes depending on the number of electronic units used in the electronic system, and can be selected and used from among them, but there are usually several types. This has the advantage that, together with the fact that the box is standardized, the layout can be easily changed and the addition of optional circuits can be easily accommodated. In addition, since the overall structure is compact, not only can volumetric efficiency be improved, but
By standardizing parts, it is economically advantageous, such as reducing the cost of parts and improving the efficiency of production management.
